[0002] Dialysis paper is used as a hard blister sealing cover material for some high-end third-class medical devices. The so-called dialysis allows some things to penetrate and blocks some things. What is allowed here are factors such as EO ethylene oxide sterilization or STEAM high-temperature steam sterilization, but bacteria are blocked out. Dialysis paper needs to be coated during the production process, and the corresponding specifications, numbers and usage methods need to be coated on the medical dialysis paper.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0035] See also Figure 2 , Figure 5 As shown, the utility model is a medical dialysis paper coating device, comprising a coating machine platform 1, a reeling device 2 is arranged on one side of the coating machine platform 1, a reeling device 3 is arranged on the other side of the coating machine platform 1, a coating machine frame 4 is fixedly installed on the top of the coating machine platform 1, a connecting platform 5 is symmetrically arranged on the top of the coating machine platform 1, a driving mechanism 6 is fixedly installed on the outer surface of the coating machine platform 1, and the inner wall of the connecting platform 5 is rotatably connected with a first connecting shaft 7 and a second connecting shaft 8, respectively, the output end of the driving mechanism 6 is fixedly connected to the first connecting shaft 7, one end of the first connecting shaft 7 and the second connecting shaft 8 are fixedly installed with a lifting worm gear 9, a connecting sleeve 10 is fixedly installed on the outer surface of the connecting platform 5, a worm 11 is slidably connected to the inner wall of the connecting sleeve 10, and a limiting component 12 is arranged at the bottom of the worm 11.

[0036] When in use, the unwinding device 2 is started to transfer the dialysis paper to be coated to the upper surface of the coating machine 1. Since the unwinding device 2 unwinds intermittently, the dialysis paper is transferred to the upper surface of the coating machine 1 in sections. When the dialysis paper is being transferred, the driving mechanism 6 is started to drive the first connecting shaft 7 and the second connecting shaft 8 to rotate in the same direction at the same time, thereby driving the two sets of lifting worm gears 9 to rotate in the same direction at the same time, and the two sets of lifting worm gears 9 are incomplete worm gears. When the dialysis paper is transferred to the upper surface of the coating machine 1, the two sets of lifting worm gears 9 continue to rotate. When the gear teeth of one set of lifting worm gears 9 mesh with the outer side of the worm 11, the worm 11 is driven to move along the inner wall of the connecting sleeve 10. The worm 11 moves downward, driving the bottom limiting assembly 12 to move downward until it is pressed on the top edge of the dialysis paper to press it. At this time, the two groups of limiting assemblies 12 are respectively located at the top edge of the dialysis paper to limit and press it. At the same time, the coating frame 4 is driven down to coat the upper surface of the dialysis paper. During the coating process, the lifting worm gear 9 rotates continuously. Since the two groups of lifting worm gears 9 rotate in the same direction, when the lifting worm gear 9 on the opposite side rotates to engage with the worm 11, it drives the worm 11 to move upward along the inner wall of the connecting sleeve 10 and moves to drive the bottom limiting assembly 12 to move upward to release the restriction on the dialysis paper. After the dialysis paper coating is completed, it continues to be conveyed.

[0037] In the utility model, the dialysis paper is intermittently transferred to the upper surface of the coating machine 1 by the unwinding device 2, and is transferred in sections. The driving mechanism 6 is cooperated to simultaneously drive two sets of incomplete lifting worm wheels 9 to continuously rotate to control the lifting process of the worm 11, so that the dialysis paper transferred to the upper surface of the coating machine 1 for coating can be pressed and limited in cooperation with the limiting component 12, so as to prevent the dialysis paper from being offset during the coating process through the coating frame 4, resulting in inaccurate coating position. In addition, the intermittent and continuous transmission of the dialysis paper by the unwinding device 2 and the repeated lifting and lowering of the limiting component 12 can continuously provide continuous transmission and coating limiting effects for the dialysis paper, thereby improving the continuity of the dialysis paper coating process and the coating operation efficiency.

[0038] In one embodiment, for the unwinding device 2, the unwinding device 2 comprises an unwinding frame 201, and a paper roller 202 is inserted into the inner wall of the unwinding frame 201;

[0039] A first motor 207 is fixedly mounted on the outer surface of the unwinding frame 201, a first rotating shaft 203 is fixedly mounted on the output end of the first motor 207, a first gear 204 is fixedly mounted on one end of the first rotating shaft 203, an unwinding gear 205 is meshed on the outer surface of the first gear 204, a second rotating shaft 206 is fixedly mounted on the output end of the unwinding gear 205, one end of the second rotating shaft 206 extends to the interior of the paper roller 202 and is threadedly connected thereto.

[0040] The paper roller 202 is mounted on the unwinding frame 201, and the output end of the second rotating shaft 206 is connected to the inside of the paper roller 202. When the first motor 207 drives the first rotating shaft 203 to rotate, the first rotating shaft 203 drives the incomplete first gear 204 to rotate. When the gear teeth on the outside of the first gear 204 rotate to engage with the unwinding gear 205, it is driven to rotate and drive the second rotating shaft 206 and the paper roller 202 to rotate. When the gear teeth of the first gear 204 are completely disengaged from the unwinding gear 205, the paper roller 202 stops rotating.

[0041] By driving the first shaft 203 to rotate through the first motor 207 and driving the incompletely matched first gear 204, the unwinding gear 205 can be rotated a certain angle to drive the paper roller 202 to rotate a certain angle, thereby controlling the dialysis paper to be intermittently transmitted, so as to cooperate with the coating frame 4 so that the dialysis paper can be continuously transmitted and coated.

[0042] In one embodiment, for the above-mentioned driving mechanism 6, the driving mechanism 6 includes a driving motor 601, a driving shaft 602 is fixedly installed at the output end of the driving motor 601, a driving wheel 603 is fixedly installed at one end of the driving shaft 602, the outer surface of the driving wheel 603 is transmission-connected with a first transmission belt 604, the inner wall of the first transmission belt 604 is transmission-connected with a main transmission wheel 605, and the main transmission wheel 605 is fixedly connected to the output end of the first connecting shaft 7;

[0043] A first transmission wheel 606 is fixedly installed on the outer surface of the first connecting shaft 7, and a second transmission belt 607 is transmission-connected to the outer surface of the first transmission wheel 606. A second transmission wheel 608 is fixedly installed on one end of the second connecting shaft 8, and the second transmission belt 607 is transmission-connected to the outer surface of the second transmission wheel 608.

[0044] By starting the driving motor 601, the driving shaft 602 is rotated to drive the driving wheel 603 to rotate. When the driving wheel 603 rotates, it drives the first transmission belt 604 to drive the main transmission wheel 605 to rotate, and then drives the first connecting shaft 7 and one of the lifting worm gears 9 to rotate. When the first connecting shaft 7 rotates, it drives the first transmission wheel 606 to rotate and drives the second transmission belt 607 to drive the second transmission wheel 608 to rotate, thereby driving the second connecting shaft 8 and another group of lifting worm gears 9 to rotate synchronously.

[0045] The driving motor 601 drives the driving shaft 602 to rotate, and cooperates with the first transmission belt 604 and the main transmission wheel 605 as well as the first transmission wheel 606 and the second transmission belt 607, so that the first connecting shaft 7 and the second connecting shaft 8 can rotate synchronously in the same direction, thereby driving the two sets of lifting worm gears 9 to rotate synchronously, and then the two sets of lifting worm gears 9 continue to rotate to control the repeated lifting process of the worm 11, and cooperate with the limiting component 12 to achieve intermittent limiting and suppressing effect on the dialysis paper.

[0046] In one embodiment, for the above-mentioned limit assembly 12, the limit assembly 12 includes a transverse insertion rod 1201, the transverse insertion rod 1201 penetrates into the interior of the worm gear 11, a fixing rod 1202 is fixedly installed on the lower surface of the transverse insertion rod 1201, a pressure plate 1203 is fixedly installed on the bottom of the fixing rod 1202, and a side baffle 1204 is fixedly installed on one side of the pressure plate 1203.

[0047] The horizontal rod 1201 is close to the bottom of the worm 11 and penetrates into the inside thereof. When the worm 11 is lifted or lowered, it drives the horizontal rod 1201 to be lifted or lowered, and at the same time drives the fixed rod 1202 and the pressing plate 1203 at the bottom to be lifted or lowered. When the pressing plate 1203 moves downward to the upper surface of the coating machine 1, the side baffle 1204 is located at the outer edge of the dialysis paper, and the bottom of the pressing plate 1203 is semicircular. When the pressing plate 1203 is pressed on the top surface of the dialysis paper, the arc surface of its bottom contacts with the dialysis paper, reducing the friction area therewith to prevent indentations on the surface of the dialysis paper, and the side baffle 1204 simultaneously limits the outer edge of the dialysis paper at the side edge to prevent it from running off, thereby having a limiting effect on the dialysis paper.

[0048] In one embodiment, for the above-mentioned transverse insertion rod 1201, a plurality of rotation holes 1205 are opened on the outer surface of the transverse insertion rod 1201, and the outer surface of the worm 11 is threadedly connected with a fixed insertion rod 13.

[0049] Since the transverse rod 1201 penetrates into the interior of the worm 11, the transverse rod 1201 is pulled to displace it inside the worm 11 to adjust its extension length above the coating machine 1, and the fixed rod 13 penetrates into the interior of the worm 11 and fixes it with the corresponding rotation hole 1205, so as to adjust the distance between the pressing plate 1203 and the inner side of the coating machine 1, so as to provide a limiting and pressing effect on the outer edge of dialysis paper of different specifications.

[0050] In one embodiment, for the above-mentioned coating machine platform 1, a drying platform 14 is fixedly installed on the outer surface of the coating machine platform 1, a mounting plate 15 is symmetrically arranged on the top of the drying platform 14, a sliding rod 16 is fixedly installed on the outer surface of the mounting plate 15, and a hot air blower 17 is slidably connected to the outer surface of the sliding rod 16.

[0051] When the hot air blower 17 is slidably installed on the outside of the sliding rod 16, and the hot air blower 17 is located above the drying table 14, after the dialysis paper is coated, it continues to be transferred to the upper surface of the drying table 14, and the hot air blower 17 is pushed to slide outside the sliding rod 16 and then start to blow hot air to the upper surface of the dialysis paper at the same time.

[0052] By slidingly installing the hot air blower 17 on the outside of the slide rod 16, when the dialysis paper is transferred to the upper surface of the drying table 14, the hot air blower 17 continuously blows out hot air while it moves laterally above the drying table 14 to increase the hot air blowing range, thereby improving the rapid and comprehensive drying effect of the dialysis paper.

[0053] In one embodiment, for the above-mentioned mounting plate 15 , a cylinder 18 is fixedly mounted on the outer surface of the mounting plate 15 , a telescopic push rod 19 is provided at the output end of the cylinder 18 , and one end of the telescopic push rod 19 is fixedly connected to the outer surface of the hot air blower 17 .

[0054] By connecting the telescopic push rod 19 to the outside of the hot air blower 17, the telescopic push rod 19 can be driven to extend and retract by starting the cylinder 18 to push the hot air blower 17 to slide on the outside of the sliding rod 16, so that the hot air blower 17 repeatedly moves laterally above the drying table 14, thereby increasing the drying range of the dialysis paper and improving the drying effect, thereby improving the coating and drying efficiency and coating quality of the dialysis paper.

[0055] In one embodiment, for the above-mentioned winding device 3, the winding device 3 includes a winding frame 301, a third motor 302 is fixedly mounted on the outer surface of the winding frame 301, and a third rotating shaft 303 is fixedly mounted on the output end of the third motor 302;

[0056] A third gear 307 is fixedly mounted on the outer surface of the third rotating shaft 303, and a winding gear 304 is meshed with the outer surface of the third gear 307. A driving shaft 305 is fixedly mounted on one end of the winding gear 304. A winding roller 306 is provided on the inner wall of the winding frame 301, and one end of the driving shaft 305 extends to the interior of the winding roller 306 and is threadedly connected thereto.

[0057] The third motor 302 is started to drive the third shaft 303 to rotate to ensure that the third gear 307 drives the winding gear 304 to rotate, so as to cooperate with the driving shaft 305 to drive the winding roller 306 to rotate to wind up the dialysis paper after coating and drying. The third gear 307 and the first gear 204 are both incomplete gears, so that the paper roller 202 and the winding roller 306 rotate synchronously, and then cooperate with the intermittent unwinding of the dialysis paper to intermittently wind it synchronously.

[0058] By setting the third gear 307 and the first gear 204 as incomplete gears to cooperate with the unwinding gear 205 and the winding gear 304, the winding and unwinding processes can be carried out synchronously, so that the dialysis paper can maintain a certain transmission rate and winding rate during the transmission process, thereby improving the coating operation efficiency.

[0059] In one embodiment, for the coating machine 1 , the outer surfaces of the coating machine 1 and the winding frame 301 are both fixedly mounted with side panels 20 , and the inner walls of the side panels 20 are fixedly mounted with guide rollers 21 .

[0060] By arranging guide rollers 21 on the outside of the coating machine 1 and the winding frame 301, the dialysis paper is conveyed along the ground of the guide rollers 21 at both the unwinding output end and the winding input end, so that the dialysis paper maintains a certain tension during the conveying, coating and winding process to prevent wrinkles and protrusions from affecting the coating effect.

[0061] In summary, with the aid of the above technical solution of the utility model, the first motor 207 is started to drive the first gear 204 to drive the unwinding gear 205 to rotate so as to drive the paper roller 202 to rotate to unwind the dialysis paper. When the dialysis paper is conveyed, it is conveyed along the ground of the guide roller 21 outside the coating machine 1 to its upper surface. When the unwinding gear 205 stops rotating, the dialysis paper stays on the upper surface of the coating machine 1. At the same time, the first connecting shaft 7 driven by the driving motor 601 rotates synchronously with the second connecting shaft 8. The two groups of lifting worm wheels 9 are driven to rotate synchronously. After the gear teeth of one group of lifting worm wheels 9 mesh with the worm 11, it drives it to move downward and synchronously drives the horizontal insertion rod 1201 and the pressing plate 1203 at the bottom to move downward to the upper surface of the coating machine 1 and press on the top edge of the dialysis paper. Then, the coating machine frame 4 is started to coat the upper surface of the dialysis paper. At this time, the two groups of lifting worm wheels 9 continue to rotate. When the external gear teeth of one group of lifting worm wheels 9 rotate to the other side and disengage from the outside of the worm 11, the opposite group of lifting worm wheels After the 9 gear teeth rotate to the same side and mesh with the worm 11, the worm 11 is driven to move upward to drive the pressure plate 1203 to move upward to release the limiting pressure effect on the dialysis paper. At this time, the first gear 204 continues to rotate and meshes with the unwinding gear 205 again to drive it to rotate and continue to unwind the paper roll 202. When the coated dialysis paper is transferred to the top surface of the drying table 14, the cylinder 18 drives the telescopic push rod 19 to push the hot air blower 17 to slide outside the sliding rod 16 and blow hot air to the dialysis paper. The upper surface is quickly dried, and at the same time, the third motor 302 drives the third shaft 303 to rotate to drive the third gear 307 to rotate and cooperate with the winding gear 304 to drive the winding roller 306 to rotate to wind up the dialysis paper after coating and drying. In this way, the dialysis paper can be conveyed and coated intermittently and continuously, and it can be limited and pressed during the conveying and coating process to prevent deviation, thereby improving the coating processing quality while improving the coating operation efficiency of the dialysis paper.

[0062] Through the above technical solution, 1. The dialysis paper is intermittently transferred to the upper surface of the coating machine 1 by the unwinding device 2, and is transferred in sections. The driving mechanism 6 simultaneously drives two sets of incomplete lifting worm wheels 9 to continuously rotate to control the lifting process of the worm 11, so that the dialysis paper transferred to the upper surface of the coating machine 1 for coating can be pressed and limited by the limiting component 12 to prevent the dialysis paper from being offset during the coating process of the coating frame 4, resulting in an inaccurate coating position. The intermittent continuous transmission of the dialysis paper and the repeated lifting and lowering of the limiting component 12 can continuously provide continuous transmission and coating limiting effects for the dialysis paper, thereby improving the continuity of the dialysis paper coating process and the coating operation efficiency; 2. By setting the third gear 307 and the first gear 204 as incomplete gears to cooperate with the unwinding gear 205 and the winding gear 304, the winding and unwinding processes can be carried out synchronously, thereby allowing the dialysis paper to maintain a certain transmission rate and winding rate during the transmission process, thereby improving the coating operation efficiency.
